Aberystwyth Grits - fault and flute casts

A small cove has formed at the seaward foot of Constitution Hill. A fault runs from top left to reach the beach in the centre of the cove. The vertical displacement can best be seen in the thicker, brownish strata at the centre of the photo. This layer is a sandstone deposit and is the bottom layer of a sandstone-siltstone-mudstone bed deposited by a turbidity current.

The coastal stretch north of Aberystwyth towards Clarach is known for its exposed turbidite beds Link and for their intricate folding and faulting patterns Link . The name of the site originates from a sea stack located on the foreshore (links above are to the Geological Conservation Review's site reports).

The Geological Conservation Review (GCR) is a database of geological reference sites in Great Britain. It is published by the Joint Nature Conservation Committee (JNCC) in the form of site reports collected in printed volumes covering different geological periods and topical areas such as fossils, minerals or geomorphology. The site reports are gradually put online in a searchable database Link .
